【摘要】 目的 探討燈盞花素注射液聯合血管緊張素轉換酶抑制劑（ACEI）依那普利治療糖尿病早期腎病的臨床效果。 方法 2006年10月-2009年12月，將59例臨床確診2型糖尿病早期腎病的患者隨機分為治療組（n=30）與對照組（n=29）。對照組在基本治療的基礎上應用依那普利，治療組在基本治療的基礎上聯合應用依那普利和燈盞花素注射液，療程均為3周。觀察治療前后兩組患者24 h尿微量白蛋白排泄率（UAER）、全血黏度、血漿黏度、甘油三酯（TG）、尿素氮（BUN）、血肌酐（SCr）的變化。 結果 兩組患者治療前后自身對比，24 h UAER均有明顯下降（Plt;0.05）；治療組UAER下降較對照組更為明顯（Plt;0.05）。 結論 ACEI聯合燈盞花素，其降低24 h UAER療效優于單純ACEI療效，還可有效降低全血黏度和血漿黏度，降低纖維蛋白原含量，改善患者血液流變性。【Abstract】 Objective To investigate the therapeutic effects of breviscapine combined with angiotensin converting enzyme inhibitor (enalapril) on early diabetic nephropathy. Methods A total of 59 patients with early diabetic nephropathy diagnosed between October 2006 and December 2009 were randomly divided into treatment group (n=30) and control group (n=29). The patients in treatment group were treated by breviscapine combined with enalapril, while the patients were treated with only enalapril in the control group. All of the patients were treated for three weeks. Urinaryalbuminexcretion (UAE), whole blood viscosity, plasma viscosity, triglycercide, blood urea nitrogen and serum creatinine in the two groups were detected before and after the treatment. Results After the threatment, UAE decreased in both of the two groups compared with the value before the treatment (Plt;0.05); the decrease in treatment groups was more obvious than that in the control group (Plt;0.05). Conclusion The combination of breviscapine and enalapril is effective on early diabetic nephropathy.
Objective To observe the effects of minocycline to the viability and apoptosis of ratprime;s retinal neuron cells (RNC) under pressure, and to investigate the neuroprotective mechanisms of minocycline against the RNC damage. Methods Establish a model of ratprime;s RNs under pressure cultured in vitro, the protective effect of minocycline is observed by different methods, including observing the morphology of the cells, evaluating the cellsprime; viability by methyl thiazolyl tetrazolium (MTT) colorimetry assay, and detecting the cellular apoptosis with acridine orange/ethidium bromide (AO/EB) double staining by fluorescence microscopy. Immunocytochemistry was used to detect the expression of iNOS and caspase-3 in the cells. Results Obvious morphology changes of RNC were found in cells under pressure compared with the control; the viability of RNC decreased and cellular apoptosis was found in 53.93% cells. The cellular morphology improved in the cells treated by 20 mu;mol/L minocycline, the cellular viability significantly increased, and the cellular apoptosis was found in 17.29% cells. In addition, the expression of iNOS and caspase3 in the treated cells decreased compared with which in the pressured group. Conclusion Minocycline with a certain concentration can effectively inhibit pressureinduced damage and apoptosis of RNC of rats, and the inhibitory effect on expression of iNOS and capases-3 may be the underlying mechanism.

Objective To observe the therapeutic effect of thermosensitive hydrogel containing curcumin-vitamin E (VE) complex (hereinafter referred to as “curcumin-VE hydrogel”) on radiation-induced oral mucositis in mice. Methods Curcumin-VE hydrogel was prepared using the synthesized curcumin-VE complex as the carrier and poloxam as the substrate. The structure of curcumin-VE complex was characterized by Fourier transform infrared spectrometer, the microstructure of curcumin-VE hydrogel was determined by scanning electron microscope, and the gelation temperature was determined by rheometer, gel swelling and degradation were tested and gel adhesion was determined using a universal testing machine. Thirty healthy male BALB/C mice with specific pathogen free grade were randomly divided into three groups, with ten mice in each group. The radiation group and radiation+hydrogel group were modeled by a single high dose of radiation (25 Gy), while the control group had anesthesia but no radiation. The control group and radiation group were given daily feed and water 7 days after radiation. In addition to daily feed and water, the radiation+hydrogel group was given curcumin-VE hydrogel twice a day. The mice were sacreficed on the 8th day after radiation. The weight changes of each group were recorded after radiation. The ulceration area of tongue was measured by toluidine blue. The tongue of mouse were pathologically observed. The activities of superoxide dismutase, catalase (CAT), and glutathione peroxidase and the level of malondialdehyde in tongue tissue were determined. The levels of tumor necrosis factor α (TNF-α), interleukin (IL)-1β and IL-6 in tongue tissue were determined by enzyme linked immunosorbent assay. The distribution and positive expression of phosphorylated histone H2AX (γ-H2AX) and nuclear factor-erythroid 2-related factor 2 were determined by immunohistochemistry. Results Curcumin-VE hydrogel had a porous network structure and the gelation temperature was 30℃, the swelling rate was close to 300%, the gel degradation rate was up to 95% after 48 h, and the adhesion strength was 12.748 kPa. Compared with the radiation group, the weight of mice in the radiation+hydrogel group increased (P<0.05), the ulcer area decreased (P<0.05); the activity of CAT increased (P<0.05); the levels of TNF-α, IL-1β and IL-6 decreased (P<0.05); the expression of γ-H2AX was down-regulated (P<0.05). Conclusion Curcumin-VE hydrogel can delay or weaken the process of radiation-induced oral mucositis by reducing the DNA damage caused by radiation, inhibiting the production of reactive oxygen species, and effectively reducing the level of inflammation in tongue tissue.

ObjectiveTo realize automatic risk bias assessment for the randomized controlled trial (RCT) literature using BERT (Bidirectional Encoder Representations from Transformers) as an approach for feature representation and text classification.MethodsWe first searched The Cochrane Library to obtain risk bias assessment data and detailed information on RCTs, and constructed data sets for text classification. We assigned 80% of the data set as the training set, 10% as the test set, and 10% as the validation set. Then, we used BERT to extract features, construct text classification model, and evaluate the seven types of risk bias values (high and low). The results were compared with those from traditional machine learning methods using a combination of n-gram and TF-IDF as well as the Linear SVM classifier. The accuracy rate (P value), recall rate (R value) and F1 value were used to evaluate the performance of the models.ResultsOur BERT-based model achieved F1 values of 78.5% to 95.2% for the seven types of risk bias assessment tasks, which was 14.7% higher than the traditional machine learning method. F1 values of 85.7% to 92.8% were obtained in the extraction task of the other six types of biased descriptors except "other sources of bias", which was 18.2% higher than the traditional machine learning method.ConclusionsThe BERT-based automatic risk bias assessment model can realize higher accuracy in risk of bias assessment for RCT literature, and improve the efficiency of assessment.
To assist grassroots sonographers in accurately and rapidly detecting intussusception lesions from children's abdominal ultrasound images, this paper proposes an improved YOLOv8n children's intussusception detection algorithm, called EMC-YOLOv8n. Firstly, the EfficientViT network with a cascaded group attention module was used as the backbone network to enhance the speed of target detection. Secondly, the improved C2fMBC module was used to replace the C2f module in the neck network to reduce network complexity, and the coordinate attention (CA) module was introduced after each C2fMBC module to enhance attention to positional information. Finally, experiments were conducted on the self-built dataset of intussusception in children. The results showed that the recall rate, average detection accuracy (mAP@0.5) and precision of the EMC-YOLOv8n algorithm improved by 3.9%, 2.1% and 0.9%, respectively, compared to the baseline algorithm. Despite slightly increased network parameters and computational load, significant improvements in detection accuracy enable efficient completion of detection tasks, demonstrating substantial economic and social value.
People with Parkinson’s disease (PD) exhibit multi-system damaged. Medication mainly targets impairments related to dopaminergic lesions. Moreover, in later stages of the disease, medication becomes less effective. Rehabilitation therapy is believed that it can improve multiple functional disorders, including myotonia, bradykinesia, and postural gait abnormalities. It not only reduces the severity of non-motor symptoms and improves the quality of life in PD patients, but also delays the development of PD and improves the activity of daily life of patients. This article summarizes the progress of rehabilitation assessment and the therapy of PD.
